Arbitrum Gets a New Way to Keep Crypto Transfers Private NullMask (@NullMaskio) is now live on Arbitrum (@arbitrum) $ARB, bringing its privacy tools to one of Ethereum's largest Layer 2 networks. The protocol lets users deposit $ETH and supported tokens into a shared pool. From there, they can send funds privately, swap assets and withdraw to any address. Users can access NullMask through their existing wallets. The launch extends NullMask's reach across Ethereum, Base (@base) and Arbitrum.

Arbitrum has had a busy few weeks since early October. @arbitrum ($ARB) is an Ethereum layer-2 network, and its tech also powers other chains such as Robinhood Chain.

Arbitrum is Pulling Ahead in The Stablecoin Race Arbitrum (@arbitrum) $ARB recorded a $5.1 billion increase in stablecoin transfer volume over the past seven days, according to Token Terminal data dated November 1. The growth comes as more stablecoin activity reaches the network. Last week, robinhood:0x5fc5360d0400a0fd4f2af552add042d716f1d168 lending TVL on Morpho (@Morpho) has climbed above $140 million, while Dolomite (@Dolomite_io) recently added USDG support. The network is also trying to bring more stablecoin activity into its DeFi ecosystem. Applications are now open for its Stablecoin Growth Program, which offers performance-based incentives and access to a 2 million ARB prize pool.

Arbitrum is the #2# chain for perps trading. @arbitrum has generated $79.6 BILLION in perps DEX volume in the past 30-days per DefiLlama data. With over $1 billion in open interest, that makes $ARB the #2# chain for perps, after @HyperliquidX itself. The vast majority of this activity is driven by the @variational_io platform.

Arbitrum lands full support from PumpFun. @PumpFun has announced that its platform is now live on the leading @arbitrum L2 network. Users on the $PUMP platform can now trade any $ARB native token, directly with their $USDC balance. PumpFun has made several similar announcements in the past few days for @ton_blockchain, @Monad, and @megaeth.
